Bought 2, one for a ml 320 and one for a ml 430. Both fit great.

I'm very satisfied. I have experienced noticeable horsepower gains, and I am very happy with the fact I will never have to buy another filter.

It seems to work, however, I haven't noticed any improvement in power or mileage. It hasn't seemed to degrade mileage or power, I just haven't noticed any significant change.

Fit perfectly, I have used various K&N filters over the past 20+ years now all of my vehicles have K&N, I would not use any other.
